Abstract

We study a two-dimensional (2D) electron system with a linear spectrum in the presence of Rashba spin-orbit (RSO) coupling in the hydrodynamic regime. We derive a semiclassical Boltzmann equation with a collision integral due to Coulomb interactions on the basis of the eigenstates of the system with RSO coupling. Using the local equilibrium distribution functions, we obtain a generalized hydrodynamic Navier–Stokes equation for electronic systems with RSO coupling. In particular, we discuss the influence of the spin-orbit coupling on the viscosity and the enthalpy of the system and present some of its observable effects in hydrodynamic transport.

具有拉什巴自旋轨道耦合的二维系统中的水动力学纳维-斯托克斯方程

本文研究了流体力学中存在Rashba自旋-轨道耦合时具有线性谱的二维电子系统。在具有RSO耦合的系统的本征态的基础上，导出了具有库仑相互作用的碰撞积分的半经典玻尔兹曼方程。利用局部平衡分布函数，得到了具有RSO耦合的电子系统的广义流体力学Navier-Stokes方程。特别地，我们讨论了自旋轨道耦合对系统粘度和焓的影响，并给出了它在流体动力输运中的一些可观察到的效应。

期刊介绍： Guided by an international editorial board, Low Temperature Physics (LTP) communicates the results of important experimental and theoretical studies conducted at low temperatures. LTP offers key work in such areas as superconductivity, magnetism, lattice dynamics, quantum liquids and crystals, cryocrystals, low-dimensional and disordered systems, electronic properties of normal metals and alloys, and critical phenomena. The journal publishes original articles on new experimental and theoretical results as well as review articles, brief communications, memoirs, and biographies. Low Temperature Physics, a translation of the copyrighted Journal FIZIKA NIZKIKH TEMPERATUR, is a monthly journal containing English reports of current research in the field of the low temperature physics. The translation began with the 1975 issues. One volume is published annually beginning with the January issues.
